Woodward’s EM-80 Electric Actuator Operates Power Barge in Panama

Retrofitted to Estrella del Mar in 2003, EM-80 still going strong after 90,000 hours

The 72MW power barge, Estrella del

Mar, was put into service in 2000 to

supply power to Santo Domingo in

the Dominican Republic. At that time

it was owned and operated by

Seaboard/Transcontinental Capital

Corporation. The power barge

contains seven Wärtsilä 18V38engines driving generators. In 2003,

diesel-generator set number 7 was

having vibration issues with the original actuator configuration. Our channel partner, Governor

Control Systems, retrofitted the engine with an EM-80 electric actuator  — which has now operated for

90,000 hours without any problems.

The Estrella del Mar was acquired by AES Panama in 2014 and supplies its full capacity to the

Panamanian national grid. It is currently moored at Bahia Las Minas, Panama.
